A vertical inertial sensor with interferometric readout
S. L. Kranzhoff, J. Lehmann, R. Kirchhoff +9
High precision interferometers such as gravitational-wave detectors require complex seismic isolation systems in order to decouple the experiment from unwanted ground motion. Impro…
Sensors and Actuators for the Advanced LIGO+ Upgrade
S J Cooper, C M Mow-Lowry, D Hoyland +6
As part of the Advanced LIGO+ (A+) project we have developed, produced, and characterised sensors and electronics to interrogate new optical suspensions. The central element is a d…
Active platform stabilisation with a 6D seismometer
Amit Singh Ubhi, Leonid Prokhorov, Sam Cooper +9
We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of…
ETpathfinder: a cryogenic testbed for interferometric gravitational-wave detectors
A. Utina, A. Amato, J. Arends +112
The third-generation of gravitational wave observatories, such as the Einstein Telescope (ET) and Cosmic Explorer (CE), aim for an improvement in sensitivity of at least a factor o…
Reducing controls noise in gravitational wave detectors with interferometric local damping of suspended optics
J van Dongen, L Prokhorov, S J Cooper +15
Control noise is a limiting factor in the low-frequency performance of the LIGO gravitational wave detectors. In this paper we model the effects of using new sensors called HoQIs t…
Compact Michelson interferometers with subpicometer sensitivity
Jiri Smetana, Rebecca Walters, Sophie Bauchinger +11
The network of interferometric gravitational-wave observatories has successfully detected tens of astrophysical signals since 2015. In this paper, we experimentally investigate com…
